Improvement in box-fasteners



NITED STATES PATENT OFFICE.

OMAR A. STEMPEL, OF MORRISON, MISSOURI.

IMPROVEMENT IN BOX-FASTENES.

Specification forming part of Letters Patent No. 173,365, dated February 8, 1876; application filed December 1, 1875.

To all w/Lom 'it may concern:

Be it known that I, OMAR A. STEMPEL, of Morrison, in the county of Gasconade and State of Missouri, have invented a new and useful Improvement in Egg-Boxes, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

My improvement consists in the provision, in a recess at frontof the sliding lid, ofa metallic plate, through which passes a pin engaging in the front end of the case, and which is secured in position while the box is in transit by a sliding plate, which is itself held in position by a seal occupying the space in the recess, into which the lock-plate slides to dis close the top ot' the lock-pin.

Figure l is a perspective view of the upper portion of a box with part ot the cover removed. Fig. 2 is an enlarged longitudinal section. Y

The box is made of the ordinary size to contain two piles ot" the ordinary cell-trays,in which eggs are shipped.

The box consists ot' a bottom, (not shown,) sides A A', endsA B B', division-piece O, extending across the box at its mid-length, and lid D, sliding endwise into place. E E are hand-cleats, by which the box may be lifted. F F are metallic cleats, provided with lips j', and secured to Vthe upper edge ot piece C, and let into and secured to the sides A A by rivets a, so that the box is prevented from spreading open at the middle.

Thesemetallic cleats I intend to inake l the subject-matter of another application for Let ters Patent.

At the Jfront end ofthe lid is a metallic lockpiece, G, firmly secured to the lid, and through this and through the part d of the lid (extending downward at thc front end) is a pinhole, H, which extends down into the end B, and whose lower end curves inward and extends to the inside of thel end, so as to give means ot' exit to any matter that `may enter the hole H. Iis the locking-pin, which is dropped into the holeH from the top. The pin may conlsist of'a common cut-nail.

The lock-piece G has a recess, G1, in which slides a plate, K, the plate being 'held down by ribs g upon the inner` sides ot' the recess G1. The arrangement is such that the plate may be slid inward to uncover the top ot' pin I, to allow the withdrawal of the pin, or slid outward to cover the top of the pin and prevent its withdrawal. The bottom ot' the recess GI is roughened at G2, so as to hold the seal G3, which is made to till that part ot' the recess lbehind the plate K when it is in its forward position, to prevent the movement ot' the plate without destruction of the sea-l.

The plate K has a recess, K', upon the lower side, which decreases in depth backward, and the piece G has a stud, g2, which, as the plate K is moved forward over the pin I, presses against ythe under side of the plate in the groove, and springs the plate outward, so as to bind it in its side guides, and so hold it in place before the application of the seal.

At the inner end of' the plate K is a Wedgeformed projection, K2, for the easy demolishing ot' the seal when the plate is driven back,

(to allow the removal ot' the locking-pin.)

I clailn as my invention- The'locking device composed of end B,

sliding lid D, pin-hole H, pin I, sliding plate.

K, and seal G2, substantially as set forth.
